# print.TwoTrellisColumns

##### Print two conformable trellis plots in adjacent columns with user control of widths.

Print two conformable trellis plots in adjacent columns with user control of widths. Left y tick-labels and left.strip are removed from the right-hand plot.

##### Usage

```
as.TwoTrellisColumns5(left, ## left is the left trellis object
right, ## right is the right trellis object
## Both left and right must have identical
## settings for number and size of vertical panels,
## left-axis labels, number of lines in main, sub, legend.
...,
pw=c(.3, .30, .01, .30, .09),
px=list(
LL=c(0, pwc[1]),
LP=pwc[1:2],
ML=pwc[2:3],
RP=pwc[3:4],
RL=pwc[4:5]),
pwc=cumsum(pw),
strip.left=TRUE,
y.tck=c(0,0)
)
## S3 method for class 'TwoTrellisColumns5':
print(x, px=attr(x, "px"), ...)
leftLabels.trellis(x)
rightLabels.trellis(x)
panelOnly.trellis(x, strip.left=FALSE, y.tck=0)
mainSubLegend.trellis(x)
emptyRightAxis(x)
```

##### Arguments

- left, right
- Conformable
`"trellis"`

objects. Both must have the identical settings for number and size of vertical panels, left-axis labels, number of lines in main, sub, legend. - x
`"trellis"`

object.- px
- These are used
`x`

-values used in the position argument of the`print.trellis`

function. The default (constructed from the`pw`

argument) makes the Left and Right panels the same width and the Middle contai - pw, pwc
`pw`

vector of five positive numbers that sum to 1. These are the relative widths of the five sections of the result: LeftLabels, LeftPanel, MainSubLegend, RightPanel, RightLabels.`pwc`

is the cumulative sum of- strip.left
- See
`barchart`

. - y.tck
- A vector of one or two numeric values.
This will be used as the
`y`

`tck`

value for the right column of panels. See`'tck'`

in`barchart`

for details. - ...
- Other arguments are ignored.

##### Details

`as.TwoTrellisColumns5`

constructs a `"TwoTrellisColumns5"`

object, which is a list of five trellis objects named ```
"LL", "LP",
"ML", "RP", "RL"
```

. `LL`

is the left labels from the `left`

input object. `LP`

is the panels from the `left`

input object.
`ML`

is the middle labels from the `left`

object; these are
the `main`

title, `sub`

title, and `legend`

. `RP`

is the panels from the `right`

input object. `RL`

is the
right labels from the `right`

input object.
`print.TwoTrellisColumns5`

is a print method for a
`"TwoTrellisColumns5"`

object. It takes left-to-right positioning
information from the `"px"`

attribute of its argument `x`

or
from an input argument. The numbers are used as the `"x"`

information for the `position`

argument to the `print.trellis`

method.
```
emptyLeftAxis,
leftLabels.trellis,
rightLabels.trellis,
panelOnly.trellis,
```

```
mainSubLegend.trellis,
emptyLeftStrip,
emptyRightAxis
```

are functions which blank out the various components of the trellis
argument and retains their vertical spacing.

##### Value

- A
`"TwoTrellisColumns5"`

object, consisting of a list containing the constructed left, middle, and right trellis objects, and an attribute containing the`px`

value.

`likert`

for the details on the motivating example.

## default equal widths of the two panels
as.TwoTrellisColumns5(PCP, PCC) ## 11in x 7in
## make left panel twice as wide as right panel
as.TwoTrellisColumns5(PCP, PCC, pw=c(.3, .4, .01, .2, .09)) ## 11in x 7in

## Size that works in default 7x7 window. 7x7 is not recommended for
## this example because most of the space is used for labeling and not

## Ordering the rows by the lengths of the positive bars and also

## The easiest way is to use the LikertPercentCountColumns function:

ylab=NULL, between=list(y=0),
strip.left=strip.custom(bg="gray97"), strip=FALSE,
par.strip.text=list(cex=.7),
positive.order=TRUE,
main="Is your job professionally challenging?")
## Ordering the rows by the lengths of the positive bars and also
## putting percents and counts on the same plot requires coordination.
## The easiest way is to order the original tables of counts by the
## order of the percent plot.

par.strip.text=list(cex=.7),
positive.order=TRUE,
main="Is your job professionally challenging?")
## percentPlot
pct.order <- percentPlot$y.limits[[1]]
ProfChal2 <- ProfChal
